Quick Answer
North Carolina ranks top 5 nationally for solar with good sunshine and competitive pricing ($22,000-$28,000 for 8 kW). The state offers an 80% property tax exemption but no state tax credit. Duke Energy provides net metering with 1:1 credit—go sooner to lock in terms. Expect 10-14 year payback with mature installer market in Charlotte and Raleigh.
North Carolina Solar Overview
From my experience:
North Carolina consistently surprises people—top 5 in the nation for installed solar. Most of that is utility-scale, but residential is catching up. The Duke Energy territory covers most of the state, and their net metering is decent but they keep trying to change it. If you are in Charlotte or the Triangle, there are tons of installer options. My advice: get in now while net metering is still intact.
North Carolina may surprise you—it's consistently ranked in the top 5 states for installed solar capacity. While much of that is utility-scale solar, the residential market is growing as homeowners recognize the state's good solar resources and increasingly competitive pricing.
[Editor's Note, Jan 2026]:Duke Energy net metering policies face periodic regulatory review. Current customers are typically grandfathered. Verify current program terms and capacity availability with Duke before installation.

Cost Per Watt
- North Carolina average: $2.70-$3.40 per watt
- Charlotte/Raleigh metros: $2.60-$3.20 per watt
- National average: $2.75-$3.50 per watt
- Premium equipment: $3.50-$4.50 per watt
Why NC Costs Are Reasonable
- Mature market: Established installer competition
- Utility-scale experience: Infrastructure and workforce exist
- Moderate labor costs: Lower than Northeast
- Good installation conditions: Weather permits year-round work
NC Solar Incentives
Federal Tax Credit (2026)
- Purchased systems: The 30% residential credit (Section 25D) ended December 31, 2025
- PPA/Lease: Section 48E still provides 30% through 2027—passed to you as lower payments
- Already installed: Systems installed before 2026 still qualify
No Federal Credit for Purchases
Without the federal tax credit for purchased systems, PPA or lease options may be more attractive in North Carolina since they still benefit from the commercial credit through 2027. (Source: IRS guidelines and DSIRE Database)
State Incentives
- State tax credit: None available
- Property tax exemption: 80% of added value exempt
- Sales tax: Solar equipment is taxable
- Rebates: None statewide; check local options
Property Tax Exemption
North Carolina offers an 80% property tax exemption for solar installations:
- 80% exempt: Only 20% of added value is taxable
- Automatic: Applied by assessor
- Example: $25,000 system adds only ~$5,000 to assessment
- Meaningful savings: Over system lifetime
Net Metering
North Carolina has net metering, but it's more limited than some states and varies by utility.
Duke Energy Net Metering
- Available: For residential systems
- 1:1 credit: Retail rate for excess energy
- Monthly rollover: Credits carry to next month
- Annual settlement: Excess trued up annually
- System cap: Limitations on total capacity
Net Metering Limitations
- Capacity caps: Duke has caps on total net metering capacity
- Changes possible: Utility has pushed for changes
- Going sooner: May lock in better terms
Net Metering Uncertainty
Duke Energy has periodically sought to reduce net metering benefits. Current solar customers are typically grandfathered, so going solar sooner may protect your benefits longer. (Source: utility tariff filings and DSIRE Database)
Time-of-Use Rates
Duke Energy offers time-of-use rate options that may affect solar economics:
- Peak hours: Higher rates when demand is highest
- Off-peak: Lower rates overnight
- Solar benefit: Can be good if production matches peak
- Evaluate carefully: May or may not help your situation

NC-Specific Considerations
Weather and Production
- Good solar resource: 4.5-5.0 kWh/m²/day
- Humidity: Some haze reduces production slightly
- Hurricanes: Coastal areas have exposure
- Snow: Light accumulation in mountains/Piedmont
- Expected production: 1,200-1,400 kWh per kW annually
Regional Differences
Charlotte Metro
- Strong market: Many installers, competitive pricing
- Duke Energy Carolinas: Territory
- Good economics: Larger homes with AC usage
Triangle (Raleigh-Durham)
- Growing market: Tech-forward population
- Duke Energy Progress: Territory
- Good adoption: Environmentally conscious area
Coastal NC
- Hurricane consideration: Proper installation important
- Salt air: Consider corrosion-resistant equipment
- Insurance: Verify coverage details
Mountain Region
- Good sun: Higher elevation = clearer skies
- Snow: Plan for winter production dips
- Fewer installers: May have fewer options
HOA Considerations
North Carolina has solar access protections:
- Cannot prohibit: HOAs cannot ban solar
- Reasonable restrictions: Can have placement guidelines
- G.S. 22B-20: State law protecting solar rights
- Get approval: Follow HOA process, but they must approve
NC Solar Rights
North Carolina law (G.S. 22B-20) declares solar energy a property right. HOAs cannot adopt rules that prevent or significantly impair the use of solar energy systems. (Source: industry data and EnergySage analysis)
